Permission on system manager to change email address of Staff

[genesis]

Hi

 

Staff email addresses have been changed now and would like to update all the staff records with their new email addresses.

 

I have access to Systems manager. and When I go into their records - Click Telephone and Emails - this are is greyed .

 

What permission I need to assign to my self for this are to be enabled, so that I can change email addresses.

 

 

Thanks
